There are three major controls on viscosity of lava.
They are:
1. Temperature – The higher the temperature of a
lava, the less viscous it is and easier it flows. In
some cases, this is partly a function of phenocryst
content and size, which increases the viscosity of
lava with increasing phenocryst size and content
as the lava cools. Primarily, it is because viscosity
of liquids decrease with temperature.
2. Silica content – the lower the silica content, the
lower the viscosity. This is because the silica
polymerizes and the chains increase viscosity. As a
result, Mg and Fe-rich, mafic lavas are less viscous
than silicic lava. Carbonatite lava, which consists of
sodium and potassium carbonate, of Oldoinyo
Lengai has the lowest viscosity of any terrestrial
lavas because it has than three percent silica.
3. Gas content - the greater the gas (volatile) content,
the lower the viscosity.
Typically mafic lava is extruded at higher temperatures
(circa 1100°C) than silicic lava (circa 750°C). As a result
mafic lavas are less viscous than silicic lavas because
of both temperature and composition.

This is true. However, flow rate can control whether
pahoehoe lava can form or not. For example the study of
historical geologic data from Kilauea and Mauna Loa
volcanoes found that only the rough-surfaced variety
of basalt lava called a'a / aa forms when lava flows at rates
greater than 5-10 m3 per second, and the smooth-surfaced
variety called pahoehoe forms at rates lower than 5-10 m3
per second. Of course, the maximum flow rate at which
pahoehoe forms varies with viscosity. There is another
form of lava called “toothpaste lava” which forms at the
transition from a'a to pahoehoe lava.

New Research About Enigmatic Front Range, Colorado, Clastic Dikes
New Research About Enigmatic Front Range, Colorado, Clastic Dikes
Clastic dikes that are found intruding downward in
Precambrian granite or gneiss have, since they were
documented in 1894, presented something of an
enigma as to their origin and source of sand. In 2013
and 2014, Dr. Christine Siddoway and others have
published abstracts and papers about these dikes
that provide important significant, new information
about them. Although these publications do not
completely answer all of the questions about these
clastic dikes, they provide answers to the age and
unanticipated source of the sand that fills them. They
indicate that these dikes are associated with faulting
that occurred during the breakup of the supercontinent
of Rodinia and where later reactivated during the
Larimide orogeny. These papers tell a very interesting
story. Articles about Christine Siddoway’s research are:

A Belated Introduction - Paul H.
A Belated Introduction - Paul H.
From what I can find, it seems like that I have not introduced myself. I am a research geologist at the
Louisiana Geological Survey at Louisiana State University in Baton Rouge. I am with the geological
mapping section as discussed in:
http://www.lgs.lsu.edu/deploy/staff/staff.php?sectionID=5
Some of the 1:100,000 scale geological maps that I have coauthored / cocompiled can be downloaded from
http://www.lgs.lsu.edu/deploy/content/PUBLI/contentpage17.php .
Some of my publications can be found at:
http://lsu.academia.edu/PaulHeinrich and
http://www.lgs.lsu.edu/deploy/content/PUBLI/contentpage14.php .
Part of what I enjoy doing and still get paid for is answering questions about geology from the general public. Although I busy, feel free to contact me at my work email address with questions that I might be able to help you with. I will try to do the best that can to get back to you in a reasonable period of time.
Best wishes,
Paul H.

Part of what I enjoy doing and still get paid for is answering questions about geology from the general public. Although I busy, feel free to contact me at my work email address with questions that I might be able to help you with. I will try to do the best that can to get back to you in a reasonable period of time.
Best wishes,
Paul H.
